After obtaining ethical approval, the study will commence within 2 weeks and continue for 1 year. Based on clinical statistics or general literature data, and considering sample size calculations, a total of 280 patients across 4 groups have been determined.
Inclusion Criteria:
Age 18 and above Patients presenting with symptoms of heart failure
Exclusion Criteria:
Age under 18 Patients presenting with ST-elevation myocardial infarction Patients with acute kidney failure Pregnant patients Patients with inaccessible data for the parameters under study
Groups based on initial mean arterial pressure (MAP) upon hospital admission will be established as follows: \<65 mmHg, 66-80 mmHg, 81-100 mmHg, \>100 mmHg. Data including results of emergency department tests and pertinent findings will be recorded for patients in these groups. The 30-day mortality rates of these patients will be statistically evaluated based on their MAP values and the procedures performed during emergency department monitoring.
